    Homebuilt Aircraft Component Factory - A good idea?

    I think the discussion as delved into the plane - building environment in some detail. Many of my questions have been answered, except for one I can think of: How do you prevent a great design being 'lost' - plans, drawings, build videos, knowledge base - at least this should be preserved in...

    Homebuilt Aircraft Component Factory - A good idea?

    In the software industry we have 'escrow agreements' might be useful to keep a plane design going, maybe some designs need to fade into history after all, I don't know. The article on the Adam A500 is what really brought up this line of thought. Adam Aircraft: (Maybe a 1/2 scale kit-built...

    Homebuilt Aircraft Component Factory - A good idea?

    As for homebuilts in Sri Lanka, there are 3 that I know of, all are in the Sri Lanka Airforce Museum, which makes you wonder. There are many Cessna 152s still flying around from the various flight schools. I can't remember the name of the kit, however. There is also a Kitfox that I was able to...

    Homebuilt Aircraft Component Factory - A good idea?

    Lots of great answers here. For the individual builder with the restriction on parts content it may be difficult to follow the practice of ordering most of the major components, and the manufacturer- assisted build programs are a great idea. How about a mass subcontractor for aircraft...

    Homebuilt Aircraft Component Factory - A good idea?

    Yes something like that: I mean, one aicraft factory that takes its orders from multiple manufacturers.

    Homebuilt Aircraft Component Factory - A good idea?

    I was looking through the Kitplanes website recently and some builders threads as well. Each aircraft is either hand built or built from materials or parts supplied from the factory - wings, fuselage etc. Given the high cost of these components and also the tooling and factory space...

    Design Exercise: Design of a flight sim aircraft

    https://en.wikipedia.org/wiki/Aircraft_design_process "Aircraft conceptual design involves sketching a variety of possible configurations that meet the required design specifications. By drawing a set of configurations, designers seek to reach the design configuration that satisfactorily meets...

    Design Exercise: Design of a flight sim aircraft

    I have revised the requirement after a little more research. The requirement for a low stall speed of 20 knots actually stemmed from the belief that lower landing speeds would make for easier and safer landings. Landing on a helipad is out of the question, however, that is best left for VTOL...

    Design Exercise: Design of a flight sim aircraft

    I have been looking at re-starting this project. Much information is covered in this aircraft forum: https://aviation.stackexchange.com/questions/65780/would-a-two-seat-light-aircaft-with-a-landing-speed-of-20-knots-and-a-top-speed/65892#65892 There have been one or two homebuilt aircraft in...

    Risk classification for accident reports?

    Only reason is age and the thinking that comes with it: was a young person I would have given anything to become a pilot, even a military pilot in a war. Now well... The only remaining fear is really engine failure after take off at low altitude just after take off. But hang on. I remember some...

    Design Exercise: Design of a flight sim aircraft

    Airplane design site with some spreadsheets. These are the easiest to use that I have seen. http://www.lightaircraftassociation.co.uk/2010/Engineering/Design/preliminary_design.html With the data for the Piper PA-28 I get a stall speed of 52.6kt compared to the actual of 47 using a life...

    Risk classification for accident reports?

    So here is the cut and paste from the FRAT spreadhsheet tool from the site here : https://www.faasafety.gov/gslac/ALC/libview_normal.aspx?id=103987 Alignment is a little awry but the risk categories give you an idea of what is important - maybe. Could not run the spreadsheet macros on my...

    Risk classification for accident reports?

    Thanks to all for a great discussion. Several things have become clear, especially the freedom you have in the the United States and your collective desire to keep it. A case in point is the practice of riding motorcyles on highways, without a helmet, for example, though laws vary from state...

    Risk classification for accident reports?

    Bob, I read Don Lancaster's article in full : very interesting because I have some ideas myself that I wanted to patent, in fact when I was in the US in 1987 I submitted two ideas to a firm that said they would help inventors. One idea was rejected as being too obvious, the other one well 'you...

    Risk classification for accident reports?

    Wll that's really unfortunate. What about the idea of requiring a flight plan and a risk asessment before every flight? With the new computer equipment and tablet devices filling in some boxes on an app should not be too difficult. About icing - did you see the AOPA video about the TBM 700...

    Modern day "motorcycle of the air" aircraft class?

    What about safety, any objection to occupant protection? Motorcyles are being designed with occupant protection cells and roll cages: Here's a CLEVER concept you may want to use to base the cabin section of your design on. http://inventorspot.com/articles/clever_concept_wellclever_14809...

    Malaysian airlines missing plane

    I am not sure if all the evidence has been listed, but I saw this in the news a while ago: http://nymag.com/daily/intelligencer/2016/07/mh370-pilot-flew-suicide-route-on-home-simulator.html (July 22, 2016) Quote "The fact that Zaharie apparently practiced flying until he ran out of fuel over...

    Risk classification for accident reports?

    "The NTSB makes numerous safety recommendations to the FAA every year" You are right, I was not aware: about 10 recommendations this year for aviation alone. It all sounds very reasonable for example: I must admit I am a bit confused - wont' that make training redundant? And its a total...

    Risk classification for accident reports?

    The decision making cycle for the private pilot will have to be restrospective - post accident incident and involve the NTSB or FAA. That's the decision loop that's available now. A retrospective analysis of risk will feed back into the pilots decision making process and training. That's what I...
